Dom,WTF LT4 resonator, might as well put bananas in your tailpipe.

Go with SW X-pipe and fatten her up a bit before you do first pull.

dominic ,i went with 2 balance tubes in my exhaust one up front and one behind the rear end just before the pipes turn away from each other . i dont have any drone and actually picked up .5mph over the x pipe at the strip

Naw...I'm w/ Pete. You spent a lot of $$ to get the Nero Rosa together; heads and cams, etc, etc. See what power she'll make first, and then fuss with the droaning, later. That way too, you'll have a base case to compare whatever changes to the system that you make later.

My suggestion.
Buy the SW X-pipe and 2 Dynomax Ultra Flo mufflers 3"inlet/ dual 2 1/2" outlets.
Cost around $450
Before you order mufflers call Al he will give you the right part # don't want you to order some grandma mufflers.LOL

Optional:
Find C6ZO6 mufflers cut off & use vacuum actuators on your Dynomax mufflers.
